Detailed Description

template<typename v_src, typename v_dst, int... prp>
struct object_si_di< v_src, v_dst, OBJ_ENCAP, prp... >

It copy the properties from one object to another applying an operation.

Given a set of properties for the destination object (0,1,3) it copy that properties to the source object properties (0,1,2) applying an operation

For object we mean an object that follow the OpenFPM data structure format, see openFPM_data wiki for more information

Create a compile-time object and copy <em>to</em> the selected properties applying an operation

    typedef Point_test<float> p;
    typedef Point_test<float>::type vboost;
    typedef object_creator<Point_test<float>::type,0,1,4>::type vboost_red;
 
    object<vboost> dst;
    object<vboost_red> src;
 
    // fill the source properties 0,1,2 with data
 
    boost::fusion::at_c<0>(src.data) = 1.0;
    boost::fusion::at_c<1>(src.data) = 2.0;
 
    for (size_t i = 0 ; i < 3 ;  i++)
        boost::fusion::at_c<2>(src.data)[i] = i + 5.0;
 
    boost::fusion::at_c<0>(dst.data) = 2.0;
    boost::fusion::at_c<1>(dst.data) = 3.0;
 
    for (size_t i = 0 ; i < 3 ;  i++)
        boost::fusion::at_c<4>(dst.data)[i] = i + 7.0;
 
    // copy from src to dst
    object_s_di_op<add_,object<vboost_red>,object<vboost>,OBJ_NORMAL,0,1,4>(src,dst);
 
    // Check the result
    BOOST_REQUIRE_EQUAL(boost::fusion::at_c<p::x>(dst.data),3.0);
    BOOST_REQUIRE_EQUAL(boost::fusion::at_c<p::y>(dst.data),5.0);
 
    for (size_t i = 0 ; i < 3 ;  i++)
        BOOST_REQUIRE_EQUAL(boost::fusion::at_c<p::v>(dst.data)[i],2*i + 12.0);
 

Create a compile-time Encap object and copy <em>to</em> the selected properties applying an operation

 
    typedef encapc<1,Point_test<float>,openfpm::vector<Point_test<float>>::layout_type> encap_dst;
    typedef encapc<1,object<vboost_red>,openfpm::vector<object<vboost_red>>::layout_type> encap_src;
 
    openfpm::vector<p> v_point;
    openfpm::vector<object<vboost_red>> v_point_red;
 
    v_point.resize(2);
    v_point_red.resize(2);
 
    v_point_red.template get<0>(0) = 11.0;
    v_point_red.template get<1>(0) = 12.0;
 
    v_point.template get<0>(0) = 10.0;
    v_point.template get<1>(0) = 9.0;
 
    for (size_t i = 0 ; i < 3 ;  i++)
        v_point_red.template get<2>(0)[i] = i + 8.0;
 
    for (size_t i = 0 ; i < 3 ;  i++)
        v_point.template get<4>(0)[i] = i + 3.0;
 
    auto dst_e = v_point.get(0);
    auto src_e = v_point_red.get(0);
 
    object_s_di_op<add_,encap_src,encap_dst,OBJ_ENCAP,0,1,4>(src_e,dst_e);
 
    BOOST_REQUIRE_EQUAL(v_point.get(0).template get<p::x>(),21.0);
    BOOST_REQUIRE_EQUAL(v_point.get(0).template get<p::y>(),21.0);
 
    for (size_t i = 0 ; i < 3 ;  i++)
        BOOST_REQUIRE_EQUAL(v_point.get(0).template get<p::v>()[i],2*i + 11.0);
